Embodiment 1

[0065] 1730g of alloy particles containing 53%Ni and 47%Al (this alloy is melted in an electromagnetic induction furnace, poured into a crucible, cooled in air, the size of the particles is reduced, and the particle size distribution of the particles<65 μm) and 130 g of pure nickel powder (99% Ni and d50 = 21 μm) was suspended in 1557 ml of an aqueous solution containing about 2% by weight of polyvinyl alcohol to prepare a coating solution. The suspension was then sprayed onto 1,000 ml of polystyrene spheres approximately 2 mm in diameter while suspending the spheres in an upward flow of air. 1 L of these balls were additionally coated with the alloy solution. The solution that is used for coating for the second time is made of alloy particles containing 53%Ni and 47%Al of 1203g (this alloy is melted in electromagnetic induction furnace, is poured in the crucible, cools in air, reduces the size of particle, The particle size distribution of the particles is <65 μm), consistin...

Abstract

A method for preparation of alcohols by catalytic hydrogenation of carbonyl compounds with hydrogen or hydrogen-containing gases in the presence of a hydrogenation catalyst of Raney type, where the catalyst is used in the form of hollow bodies, Preferred as catalytically active components are nickel, cobalt, copper, iron, platinum, palladium or ruthenium.

Description

technical field [0001] The present invention relates to an improved process for the production of alcohols from carbonyl compounds which comprises the catalytic hydrogenation of carbonyl compounds with hydrogen or a hydrogen-containing gas in the presence of shaped Raney-type hydrogenation catalysts. Specifically, the present invention includes methods for producing sugar alcohols. Compared with the currently known methods, the method can use a relatively small amount of catalyst in the process of producing alcohol, and has the same or higher yield. [0002] According to the invention, the term carbonyl compounds refers to all organic compounds containing the =CO group, in other words also compounds containing the O=C-O group. Thus, the term carbonyl compound stands for ketones, aldehydes, carboxylic acids, carboxylates, anhydrides, esters of carboxylic acids, amides of carboxylic acids and halides of carboxylic acids. Background technique [0003] Alcoh...
